Another legislative session is about to get underway in Minnesota, and anyone with the ambition, the time and the travel resources can get a front seat to the legislative process. The House and Senate both have public galleries. Most session days feature up to a dozen committee hearings, all open to the public. And technology, from the Legislature’s website to social media sites like Facebook and Twitter, offer increasingly real-time views of Capitol happenings. The session that starts Tuesday will have Democrats fully running the Capitol for the first time in years, and there are likely to be hot debates over tax increases, gay marriage, gun laws and plenty of other issues.
