If Trump doesn’t like it, it must be a lie...
The fact is, Trump has changed a lot of positions on major issues since he started running for President. Trump is quite right to say that his speeches since last June have been consistently orthodox. However, Cruz is pointing out that for his entire adult life up until last June, Trump had been consistently Pro-Choice, Pro Big Government, Anti-2A and a whole bunch of other positions consistent with being a run-of-the-mill New York businessman.
There is nothing wrong with having those positions. Millions of New Yorkers think the same thing. There is also nothing wrong with changing those positions something more consistently conservative. We should encourage every Pro-Choice, Anti-2A, Pro-Gov person to come over to our way of thinking.
But it is not wrong to suggest that the voters should look at such a dramatic shift and evaluate whether the politician who has changed positions for the duration of the campaign can be counted on to maintain them after election day.
And those claims are wrong or inaccurate. That is the problem here. See section 3 of post 152 above, just for starters, in which Trump explained his rejection of partial-birth abortion in July, 2000. PBA had only been invented in 1983 and only reached the public's attention around the year 2000. So once he researched it, he rejected it pretty quickly. What other real estate construction boss do you know of who concerns himself with the details of feminist policies? He hadn't been familiar; but as soon as he was, he changed position. That does not qualify as "for his entire adult life" on any measure whatsoever.
As to the claims of being against the 2A, that is plain ludicrous.
