So if you are in fact a conservative who wants to cast a vote for the candidate who truly means to deliver on a promise to limit the size of government, cut federal spending, and safeguard the rights of the individual, to what party do you turn?
Not the Republicans, that's for sure. Some of them talk a good game, but what they actually do is a different story. That being the case, the voter who actually wants government off his back may as well stay home come election day.
The Republican party is the better of the two for those things you list. However, you're leaving off half of what makes a paultard. They also believe loopy info-wars conspiracy theories, abandoning Israel, that it's okay if Iran gets nukes, that a wall along the Southern border might be used to keep Americans from fleeing to Mexico, etc - you know the crazy stuff that makes it impossible for Ron Paul to really get an traction beyond his drug addled college mushhead following.

Most people realize that general elections are simply a choice between the 2 tickets that have any chance of winning. Voting for the least bad option is the norm in 2 party systems. It sucks, but that's just how it is. Maybe once or twice in your lifetime will you really have someone to get excited about voting for in a general election.
Paultards do not have some constitutional right to be in the GOP. If they aren't going to support it's nominees, then they should just go away. Maybe try taking over the Democrat party and see if they are more agreeable to an insurgency within their ranks who have no intention to support the actual party nominees.
