But you've got time to bitch and moan on an internet message board. I get it.
The time I spend on FR wouldn't make a dime's worth of difference if switched to in-party activism.
If something is important you'll MAKE the time. Giving up on the most conservative of the two electable parties is cowardly
How is voting third-party in any given race "giving up on" the GOP?
In the same way that bedding another person "giving up on" your current partner. As imperfect an analogy as it is, the familial/marital to this political/societal one is the best I can currently provide.
One of two parties is going to occupy the White House: Republican or Democrat. If you're conservative, voting third party is akin to voting for a Democrat.
Uh, I suggest you ask Al Gore about 3rd Party votes.

Read about Teddy Roosevelt & the Bull Moose Party (Progressive Party - but not the commies of today) and William H. Taft - which resulted in Woodrow Wilson.
