Yes, no one thinks that Trump is running for minister of the nation, he is running for President, to deal with issues that the President can deal with.
Presidents appoint Judges and Justices. Party platforms outline ideals. Trump is ABSOLUTELY DEAD WRONG suggesting this change to the Republican Party Platform, and bloody stupid letting the abortionist leftists at NBC (who will never in a million years vote for him) buffalo him. The proper response is "The Platform is just fine the way it is, Savannah. I absolutely wouldn't change a thing." Little moments like these really reveal where politicians truly stand. His instinct is to cave in on abortion. That's disturbing.
