Let's talk today about City Council politics and Philadelphia's Nov. 3 general election in terms of - What if?

What if two well-known local politicians formed their own political party?

What if they ran as a team for two of the seven Council at-large seats set aside in the City Charter for a minority political party?

What if intramural feuds in the Republican Party, which has held those two set-aside seats for decades, left the current GOP at-large Council members politically vulnerable?

What if the new two-man political party won?

What if City Council, starting in January, had a pair of members who could work with new and returning members to create a disruptive faction bent on changing the way the city does business?

What if Bill Green and Sam Katz take the plunge and do all that?

There's been gossip. Now, we get to find out.

Green and Katz would need to start circulating nomination petitions this week to make the deadline of next Monday, Aug. 3, for third-party candidates to get on the general election ballot.

Each would need the signatures of 1,325 registered Philadelphia voters.

Green and Katz declined to comment last week about their plans.

Green was elected to a Council at-large seat as a Democrat in 2007, won a second term in 2011 and then resigned last year when then-Gov. Tom Corbett made him chairman of the School Reform Commission. Gov. Wolf removed him from that post this year. He remains an SRC member for now.

Green registered as an independent in March.

Katz ran for mayor three times as a Republican, losing the 1991 primary election and 1999 and 2003 general elections. He now runs a documentary film company that is developing two films about the World Meeting of Families and the visit here by Pope Francis.

Katz registered as an independent in February.

This year, both men first kicked the tires on independent campaigns for mayor.

Katz signed up a campaign manager and was planning fund-raisers when he pulled the plug on the idea in mid-May.

Green last month said he would take a "clear-eyed view of the prospects" of a campaign. The odds of defeating Democratic nominee Jim Kenney, Green's old sparring partner on Council, in a mayor's race are slim.

Katz has said he hoped Green would run for mayor. Green has said he hoped Katz would run for mayor. They're pretty impressed with each other.

Sounds like a team, no?

The two guys with the most to lose in this scenario are Republican at-large councilmen Dennis O'Brien and David Oh.

O'Brien served in the state House for 35 years before winning a Council seat in 2011. Oh ran for Council three times before winning a seat in 2011.

Both have strained relationships with their party, which did not endorse them or anyone else in May's primary election.

A Green-Katz ticket could also bump off newcomers Andrew Stober, a former Nutter administration official, and Kristin Combs, a public-school teacher, who are running for the two set-aside at-large seats.

Stober is running as an independent; Combs is on the Green Party ticket.

If Green and Katz do run, who really wins? Anyone interested in a general election worth watching.

There are nearly a million voters in the city - 79 percent are Democrats, 11 percent are Republicans, and 10 percent are independents or belong to smaller parties.

What if giving them more options for voting in the general election makes them winners, too?
