Bummer day for libertarians: The 16th Amendment to the Constitution, providing for a federal income tax, was ratified on this day in 1913. And for fans of early rock 'n roll: Buddy Holly, Ritchie Valens and J.P. "The Big Bopper" Richardson died in a plane crash near Clear Lake, Iowa, on this day in 1959.

Gov. Mark Dayton will provide remarks at the 2015 Explore Minnesota Tourism Conference (Saint Paul RiverCentre, Ballroom, 175 West Kellogg Boulevard, Saint Paul.) Noon. Open press. He'll meet with commissioners, legislators, and staff throughout the day and then host a reception at the Residence for legislators. (I asked a legislator about these early legislative receptions. The question was met with an eye roll to indicate how much Dayton enjoys doing them and/or how charming he is at these events.)

Number two

MinnPost with a profile of Lt. Gov. Tina Smith. As if on cue, Smith will travel to Duluth to tour Ikonics Corp. today. In the afternoon, she will tour the Delta Airlines Iron Range Reservation Center in Chisholm. Both closed to the press. At 2:30, she will host a roundtable discussion on broadband Internet access in Chisholm (Delta Airlines Iron Range Reservation Center, Large Conference Room, 601 Oak Street, Chisholm.) That's open press with an avail.

House HHS considers loan forgiveness for health workers in rural Minnesota.

Funny House Commerce agenda: "The committee will tour production facilities regulated under Chapter 340A." Google "340A" and you'll see it's about various types of booze.

Full legislative schedule.

The price of politics

Major campaign finance data dump today; report will include final period of the 2014 campaign.

Expect the CamFi board to come back momentarily with a final advisory decision on Sen. David Tomassoni's new job as executive director at RAMS, which has traditionally lobbied the Legislature, though he says he won't be doing so. As he said to reporters Monday after the Senate session: "I don't lobby in the Legislature. People lobby me. That's how this job works." He also said he hired lawyer/lobbyist Michael Ahern to be his lawyer because "Why wouldn't I hire a lawyer who knows what he's doing and that I know and that I trust?"

Legislature continues its assault on the State Lottery's newer game delivery platforms, such as online, gas station pumps and ATMs. Story.

The Strib's David Shaffer reports an administrative law judge blames Xcel for cost overruns of its major upgrade of the Monticello, Minn., nuke plant; ratepayers may still be on the hook.

Guilty verdict in police officer's killing.

Pretty sweet, for us.

Finally, the Senate had a nice tribute Monday to retiring Pioneer Press reporter Bill Salisbury and our own late Jim Ragsdale, who also had been a longtime Pioneer Press reporter.

Washington

The Strib's Jim Spencer reports an Obama proposal for one-time tax on foreign profits, to be used for infrastructure, would hit some Minnesota companies.

Times: Republican primary caught up in vaccination issue.

Times: Christie has fancy tastes.

John Judis co-wrote a book in 2002 called "The Emerging Democratic Majority," which was an explicit echo of Kevin Phillips' 1969 book, "The Emerging Republican Majority." Judis argued then that a growing non-white vote share plus college-educated whites would give Democrats a lasting edge. It was mostly correct, as Democrats have won the popular vote in five of the past six presidential elections. Now he thinks the tide has turned. Dems continue to lose working class whites, and 2014 showed they are now also slipping with college-educated workers who make between $50 and $100k. This would seem to be a national and not so much a Minnesota trend but worth a read.

Uh, what? In Politico Mag, a member of the Warren Commission worries they got it wrong.
