|An easy call: No.|
Senator Cruz claims he wants to repeal "every word" of Obamacare and abolish the IRS. Neither will happen, nor should it. Both are simpleminded positions. If the Affordable Care Act is flawed, let's fix it. Citizens need access to health care and shouldn't be made to wait while Republicans destroy one system and then talk about whether to replace the Act from scratch. As for the IRS, they can't do anything Congress doesn't allow them to do. So Congress needs to tighten the controls and simplify the tax code. Good luck on either of those things happening.
Cruz is trying to nail down the right flank of his party, where the Primary voters tend to come from. He is far down in current preference polls, and it will be interesting to see how much support he can gin up.
