And besides, what alternative do you have for the next 4 years or when the next election comes?
From all the negative threads about Pres. Bush on here lately, I'd say that when the next election comes you may have Hillary or someone of her ilk as your "Commander in Chief".
The danger won't be from conservatives voting for Dems, it will be from them either voting third party or staying home. We all saw the importance of high vote turnout last November. If Republican candidates enrage part of their base and lose future elections, they will have only themselves to blame.

None. Until a viable third party somes along, voting for them is masturbatory - it makes you feel good, but accomplishes nothing.
