Trump at 20% in national polling, leading all other Republicans.

Trump’s 20 percent is the largest tally for a Republican contender in any national poll by the independent Quinnipiac (KWIN-uh-pe-ack) University. Behind Trump are Wisconsin Gov. Scott Walker with 13 percent and former Florida Gov. Jeb Bush with 10 percent. No other Republican tops 6 percent and 12 percent are undecided. [Quinnipiac]

ONE WEEK before the FNC Republican debate Donald Trump sits atop the Republican 2016 field, with Senators Rand Paul and Marco Rubio gasping for relevancy. Trump’s cleared away the ankle biting politicians who were once thought to be possible contenders. It’s all good news for Democrats.

Rubio was leading the field with 14 percent support in a June 2 poll from CNN. In the same poll on July 26, Rubio tied for fifth place, with 6 percent.

Rubio was polling seventh in Iowa, the state with the first presidential nominating contest, according to an NBC/Marist poll on Sunday. In New Hampshire, Rubio was in fifth with 6 percent, according to a Monmouth University poll released on Tuesday.

“I don’t know where Rubio fits in this cycle, or how he distinguishes himself,” said Charlie Bass, a member of Mitt Romney’s presidential steering committee in 2012 and a former U.S. House lawmaker from New Hampshire. “A lot will depend on his presentation in this first debate. That will be an important moment.”

Unlike Senators Ted Cruz, Lindsey Graham and Rand Paul, Marco Rubio decided to fold his Senate campaign efforts. The reaction financially was that donors of his Senate campaign had to give permission for him to funnel that cash into his presidential efforts. Many did not, according to Bloomberg Politics.

Yet Marco Rubio had $9.86 million in the bank, according to Bloomberg, as of July 1, which was the most of any Republican.

John Kasich raised $11 million after announcing. It is a steep, steep climb for him, but if he can get earned media and a boost from the debate he may have a slim shot.

It’s still very early.

Next week’s debate, which now will included all 16 candidates (some at 5 p.m., some at 9 p.m.), is going to be fascinating.

But how do you prep for a debate that has Donald Trump at center stage?
