I am somewhere between conservative and libertarian depending on the issue. Blind devotion to a political party is foolish and frankly dangerous. As a conservative, particularly on fiscal matters...I would be lying to myself if I tried to convince myself that all Republicans are the fiscal conservatives they claim to be. Devotion to an ideology is more logical in my view, if you believe that your ideology is the most practical in achieving the best outcome. But political party members are rarely devoted to anything other than solidifying their own power.
In my view...being an independent, which many people are is usually just a sign of someone who does not follow political issues very closely, and are swayed often too easily by rhetoric. I have always found it incredible how many people don't decide who to vote for until the last two weeks before the election. They may be well intended, but usually misinformed about key issues.
As far as why I am a conservative/libertarian...that would again depend on the issue. But generally speaking, political figures are either corrupt before they get into office, or easily corrupted after they get elected. A true conservative believes that role of gov't should be very limited as the founders articulated, because of this penchant for corruption. Ideally limited to those things which cannot be plausibly provided for privately. (Courts of Law, Emergency Response...etc).
The inherit corruption among political officials is precisely why gov't should be decentralized, with a substantial amount of power residing locally. Unfortunately, the political left wishes to centralize power in gov't bureaucracies all too often...which is how we get stuck with disasters like common core standards in our kids classroom, and makes it impossible for me to support their agenda. And far too many within the Republican establishment masquerade as conservatives, but are really not much different, if at all.
As George Washington once said..."Government is not reason; it is not eloquent; it is force. Like fire, it is a dangerous servant and a fearful master."
As such my trust in gov't is very limited. And our elected officials consistently prove me correct.
