Link round-up

We had nearly-perfect weather this past weekend, so I'm just dumping a bunch of links right now while I catch up with work:

• Foursquare reports that Trump's presidential campaign is really, really hurting his businesses.
• Chicago's U.S. Cellular Field (the minor-league park on the South Side) will be getting more events now they've worked out a deal with the Illinois Sports Facilities Authority.
• Wired reports on how scary-easy it is to hack electronic voting machines.
• Paul Krugman puts out the economic case for massive deficit spending on infrastructure. (This is why we need to win the House.)
• Josh Marshall plainly states that, if you're against Trump, you have to vote for Clinton.

Back to the mines.
