Will conservatives unite behind John McCain?

The more conservatives hear from Barack Obama and Hillary Clinton, the more difficult it will be for conservatives to sit out the election this November. Still, conservative have doubts about McCain and Former US Senator Rick Santorum explains why:

Why are so many conservative Republicans upset about the inevitable nomination of Sen. John McCain, and what are we going to do about it?

The cause of conservative discontent isn't hard to fathom. Start with the Arizona senator's voting record on many key issues. He has opposed pro-growth tax cuts and supported limits on political speech. He has pushed amnesty when it came to illegal immigration and half-measures when it came to interrogating terrorists. He wants to close Guantanamo and allow the reimportation of prescription drugs into the United States. Not only does he part company with conservatives on these and other issues - climate change, drilling for oil in the Alaskan hinterland, federal funding of embryonic stem-cell research, international criminal courts, gun-show background checks - he invariably adopts the rhetoric of the left and stridently leads the opposition.

It's understandable as to why conservatives don't look forward to a federal government completely controlled by the Democrats and would prefer to elect a Republican president this November as a check against the Democrat Congress. But McCain's record of working with Left wing Democrats in the Senate means that a McCain presidency might not provide as much of a check against the Left wing agenda as we would like.
