Like many Trump arguments this is a fairly disingenuous argument since he never was in office so he never cast a vote on the authorization, funding or anything else regarding the invasion of Iraq. To compare his position with Clinton's isn't the same because his opposition in 2002 didn't didn't have any political consequence. Also as Major noted his opposition appears to have come out more after the invasion had happened and the occupation was already going bad.
People who want to lodge hyperbolic insults on behalf of their partisan alliance without any exploration of facts or history.

Anyway I doubt this will be much of an issue if both Clinton and Trump make it to the general. Hillary Clinton has already dealt with this issue and while it hurt her in 2008 it wasn't the primary issue that cost her the nomination. Sanders has brought this issue up but it isn't a primary line of criticism of Clinton. By the time of the general this issue will largely be played out. If this was the 2006 election it likley would have more traction but then again Clinton won her Senate race in 2006.
The 2006 election was a pushover. It was a significant democratic state and the entire party backed her. The only real opposition she ever faced was Obama and she lost. She just doesn't handle opposition well and it shows.
In the 2008 election, Clinton name was well known but wasn't someone with much experience and was a clear favorite. She was a 2 terms Senator. Obama was a one term Senator. In mid 2006 to early 2007, there were 3 front runners: Clinton, Obama, Edward. It was not an entire party backing her or she was a clear front runner. Nothing like today.
Also Clinton still ran one of the longest losing primary campaigns in modern history at a time when both parties have been changing the rules to try to wrap up the nomination early. She won most of the large states in the Democratic primaries and matched Obama well in vote totals. Anyway the issue of her vote on the Iraq AUMF is pretty old news and I doubt Trump brings anything new to it.
