Mayor Rahm Emanuel quietly has cranked up his campaign fundraising machine, with an eye on possibly running for a third term — or at least making sure he isn't considered a lame duck for the remainder of his second one.



He's raised $316,600 since May 1, including $244,100 last month. The mayor reported raising $70,300 at a June 27 fundraiser and nearly $80,000 the following day. Emanuel had about $42,000 on hand to start the April through June fundraising quarter.



But what about some of the other politicians whose names have been bandied about in connection with a possible 2019 mayoral run?



Cook County Sheriff Tom Dart, who mulled a mayoral run in 2011, reported raising $8,291 in June, and he collected about $45,000 in the first three months of 2016. He had $422,395 to start the second quarter, according to state campaign finance records.



Chicago City Treasurer (and Emanuel ally) Kurt Summers has been consistently fundraising since Emanuel appointed him to his seat in late 2014, giving Summers a leg up in the February 2015 election. In the first quarter of 2016, Summers raised $107,000, and he had about $253,000 on hand to start April. He hasn't reported much fundraising activity since then.



County Board President Toni Preckwinkle flirted with a run against Emanuel in 2015, before deciding to stick with her county post. She raised $335,000 in the first quarter of the year and gave $250,000 to political protege Kim Foxx, who won the Democratic nod for state's attorney. That left the County Board president with $216,000 to start April. Preckwinkle has raised $168,900 since then, most of it last month.



Emanuel's top challenger from the last election, County Commissioner Jesus "Chuy" Garcia, hasn't done much on the fundraising front. He reported raising $11,000 in the second quarter, which he began with about $13,600, records show.



Chicago Teachers Union President Karen Lewis, who explored a run against Emanuel in 2015 before receiving a cancer diagnosis, still has an active "Citizens to Elect Karen Lewis Mayor of Chicago" campaign fund, state records show. She has $39.72 in her campaign fund and still owes herself $34,000 from a previous loan.



There is one Chicago politician who has not been mentioned in connection with a possible mayoral run, but he has nearly 10 times the amount of campaign cash of these other six possible candidates combined: 14th Ward boss Ed Burke. The 72-year-old City Council veteran has raised $126,500 in the second quarter, most of it since May 31.



All told, the 47-year alderman and chairman of the powerful City Council Finance Committee has amassed a staggering amount of campaign cash over the decades in his three campaign funds: $10,411,109, to be exact. (Bill Ruthhart)
