Remember when Trump fired Blagojevich over Harry Potter?

Add an argument over Harry Potter with a former Illinois governor to the list of what makes Donald Trump's presidential candidacy unique for political observers.

Millions watched in 2010 as Trump grew impatient in the board room on NBC's “The Celebrity Apprentice.” A team reporting to him hadn't performed to his expectations. Trump appeared to have no reservations posing tough questions to the beneficiary of thousands of dollars of his campaign donations.

He pointed his fingers to his chest.

“I just want to ask this one question,” Trump said.

“Your Harry Potter facts were not accurate,” he said. “Who did the research?”

Former Illinois Gov. Rod Blagojevich didn't have an acceptable answer.

“But it's Slithering and it's Hufflepuff and it's Ravencloth ...” Blagojevich tried to explain later, making any serious fan of the books wince.

He was fired from “Celebrity Apprentice” shortly after. His team had lost the challenge.

Republican Trump gave the Democrat $7,000 last decade and called it a “tragedy” in 2011 when Blagojevich was sentenced to 14 years in federal prison, a comment made at a time when sympathy for the former governor wasn't widespread.

On March 15, Trump will try to prevail in Illinois' primary to further cement his GOP front-runner status.

U.S. Rep. Robert Dold, a Kenilworth Republican, took to CNN Wednesday to say he wouldn't support Trump in the general election.

His beefs, which are perhaps the loudest among top Illinois Republicans, are with Trump's comments about Muslims, women and Sen. John McCain's military service.

“I think Donald Trump has disqualified himself,” Dold said.

Dold has not endorsed Florida Sen. Marco Rubio, Ohio Gov. John Kasich or Texas Sen. Ted Cruz in the meantime.

Lots more people are voting early in suburban Cook County than four years ago, at least so far.

Clerk David Orr said voting on Monday's first day broke a record.

As of noon Thursday, 18,765 had cast early ballots, according to Orr's running total online.

“This election we have races from president to countywide offices that are generating a lot of interest, and voters appreciate the convenience of being able to vote before Election Day, on their own schedules,” he said in a statement.

U.S. Rep. Peter Roskam held a hearing this week about free speech at colleges, pointing to their tax-exempt status.

“Under these provisions of tax law, taxpayers give financial benefits to schools based on the educational value they offer our society,” the Wheaton Republican said in his opening. “When colleges and universities suppress speech, however, we have to question whether that educational mission is really being fulfilled.”

“Schools enact speech codes to stop teasing and require the reporting of 'micro-aggressions,'” he continued. “Students shout down speakers because they disagree with the ideas they're hearing presented.”

Roskam says he's heard from faculty and students that have gotten problems when, for example, they publicly opposed Planned Parenthood.
