Growing GOP optimism for Trump chances

There appears to be growing confidence in Donald Trump's ability to win in November, according to a Politico article this morning:

GOP insiders: Maybe Trump can win

Once resigned to a November defeat, swing state Republicans are increasingly optimistic about Donald Trump’s chances now that the GOP presidential nominee has closed a once-yawning deficit in the polls against Hillary Clinton.

That’s according to The POLITICO Caucus — a panel of activists, operatives and strategists in 11 battleground states, 10 of which President Barack Obama carried in 2012. While a majority of GOP insiders still say Clinton would carry their state if the election were held today, significantly more Republicans now say Trump would win than even just a few weeks ago.

But this growing optimism is tempered by serious concerns about, among other things, the Trump campaign's ground game:

GOP insiders are mostly downcast about the state of Trump’s organization. Only 17 percent said they have “a lot of confidence” in the Trump campaign infrastructure in their state, while 39 percent have “only some confidence” in the campaign, and 44 percent have “no confidence at all.”
