The problem with your thinking is that by taking away mortgage deductions and deductions for child dependents you think that somehow single workers without mortgages will start paying less. The government will never give anything back, they will only take more and more.
Santorum defending tax credits for homeowners and families with kids is something, as a conservative, I support. To attack him as some sort of big government liberal for defending against tax increases is bizarro world stuff.
I dont think that at all. Try not making stuff up.
I am not in faor government tax policy to influence behaviors and punish other ones.
