Alright, I'll have to clarify. Supporting an opinion proposed by another candidate, in the last minute, only in a desperate attempt to "steal" voters from them, but providing no further explanation (oral or written) on its establishment is mere pretending, especially when the other side has already done it and presented examples of it here and there. So far, Clinton's speeches include a mandatory "I'm pro socialistic legislation" with no examples of actually enforcing it.
We may disagree ideologically, and what I see as profitable investment (long-term) seems pipe-dream to you, but we can both agree on the following. A person who has no real ideological basis cannot be considered a serious candidate. Of course, they will turn to their voter base, but their position requires they create an environment profitable for all. A president can fall when the people are dissatisfied, even if the media back them up, long before they even receive the party's nomination. Also, if someone is constantly verbally assaulting ethnic groups that belong to minorities, the support votes are ones that will follow the candidate until he says something offensive for their group/ethnicity/social status/etc. It's not a steady voter-base, just one that agrees with certain "hate policies", as I like to call them.
At this point I believe Sanders is the most suitable candidate because he is steady and his ideas are the ones I can agree with, at least more than the other two, who sway from right to left (or right to far right) and back. I regard them as idiots and dangerous respectively, and even if I live across the Atlantic (which means I can see this whole thing from a different point of view than the average American), this election will affect me, given your country's external policy.
That's an inherent flaw of the elective system. The absense of multiple parties allows sponsorship and inclined media coverage, thus indirect effect on the masses without clarity. A good part is the debate system, in which people from a seemingly common background are supposed to compare their suggestions and future plans both short-term and long-term. However, it's not enough, because (if we disregard the (already high) probability of it getting rigged) the way this voting system works, the smaller states have "stronger votes" than the bigger ones, thus a candidate may gain fast majority by supporting certain areas (eg by being a citizen of that area) and not even care about others. This in the end leads to a minority parliament. You can see that this relates to our topic by checking whom each candidate appeals to. Yes, Trump (for example) hates everyone, and focuses on certain classes of people, while Cruz, even if less appreciated, is still there because he chose the 'correct' groups to support.
edit for Jericho:
The constitution needs to clear at what it defines and prohibits. Whatever is not restricted by the constitution and laws (in your case defined by each state) is allowed, and should be respected.
Since abortion is a hot topic, I'll answer this even if it wasn't a question aimed at me.
When a life is unwanted before birth, it will be afterwards as well. Abortion stems from the inability to raise an infant, and dropping it to the nearest institution is a similar way of getting rid of it. While it may be a pity to kill a person, since humans are species of high thinking potential (taking a look at it from an evolutionary point of view), the changes in the mother's physical and mental state, as well as her future obligation in the upbringing of the child (hormones make it extremely difficult to take it away once it's born - thus leading to depression when there's no feedback) can cause harm, avoidable by the choice of abortion. Even if we simplify this, one has the right to choose what they do with their bodies. From an embryological point of view, the early period in which abortion is even probable, the embryo is not a "human" life form, since it more resembles a parasite than a baby (heart not pounding, appearance of a fish/lizard, undefined gender, skin and brain are still interconnected etc), so there go the religious arguments on it. I believe that a forcing "pro-life" legislation is forcing multiple choices on all people involved, thus indirectly denying them the right of freedom of choice.
