Wrong.
We'd favor the tax cuts and just state McCain was trying to repair his image somewhat with conservatives for his '08 run. Purely motivated by self interest. :-)
Actually, in seriousness, conservatives would simply ask what's the catch. McCain "endorsed" Blackwell a few months ago and conservatives haven't pulled their support from him. Ditto Bush in '04. The difference, perhaps, is that Shadegg was not a known quality so a FEW raised questions about Shadegg. I just consigned it to Mccain wanting to make connections for his '08 run, and others to in state courtesies. That's by far what the majority did in response to that endorsement.
BTW, conservatives favor less spending. McCain claims to be for less spending. Conservatives aren't endorsing more spending out of spite.
When McCain endorsed Shadegg, within 10 posts here on free republic, people all ready were ready to turn on Shadegg, and within 15 posts, 2nd guessing Shadegg.
McCain endorses anything that will get him near a camera.
FWIW, McCain claims to support less spending, there are freepers who refuse to accept that, I think McCain is just anti-pork (which is good), but a few folks here, and follow any McCain thread, start venturing out into what kind of spending McCain wants to cut.
