...I see no value in a Trump presidency.

I don't believe anything he says.

so expect most gun owners to hold their nose and vote for Trump, even if they aren't sure about where he stands.

Very true.

and he actually has a New York carry permit.

Conversely, Hillary praises the Australian model of involuntary gun buybacks, i.e., confiscation and bans, and claims to want to repeal the PLCAA.

If you were a one-issue, firearm rights voter, your election choice is unfortunately quite clear, and I anticipate that it might make a difference in swing states like Colorado, Florida, Ohio and Pennsylvania.

even the ones I like.

There are lots of them.

There are people, many people, who will not vote for Clinton for this reason alone.

He also says his sons own firearms, enjoy shooting their weapons and are quite knowledgeable about firearms in general.

That trumps Mitt Romney. "I'm not a big-game hunter," Romney said, then explained that his preferred prey were rodents, rabbits, and such--"small varmints, if you will."

Gun owners were not all that enthusiastic about either McCain or Romney as they were viewed as RINOs especially when it came to the gun control issue. Many gun owners feel that if strong gun control passes it will occur when a Republican is sitting in the Oval Office.

It remains to be seen if they will support Trump but you can bet that a high percentage of the estimated 80,000,000 gun owners do not support Hillary's position on gun control. If they show up at the polls they may make the difference in a close election.

Time will tell.

To the surprise of no one, Donald has not been shy about posting the photos of the various exotic hunts and kills.

Trump's support for gun rights may not be as absolute or proven as some of his fellow Republicans, but there is no doubt he's much stronger on the issue than Hillary, who has (just like Bernie) "evolved" a far more more stringent gun control platform during our heated Democratic primary.

I will assume Clinton will try to "pivot" back to more moderate gun stances during the general election, particularly in swing states in the south and midwest, but the Republican commercials with her recent anti-gun rights positions and statements will be clear and unmistakable, to say nothing of how the issue may play in the debates.

Equally important to many voters, the NRA endorsed Trump today.

While the NRA's comments about Clinton are disingenuous, the endorsement will still carry a great deal of political weight and will help definitely unite Republicans against Clinton (rather than necessarily in support of Trump).

for the general election.

Her problem is the that gun owners have long memories.
