"Bridge the gap" is a very common expression in the English language, as the article points out. I especially like the last sentence in the first paragraph, which refers to bridging political gaps, both inter- and intra-party.
Our system of government, with its separation of powers and checks-and-balances, is based upon compromise - or "bridging the gap." The use of committees, with members of both parties as members, in both Congress and the Senate is another manifestation of this. The idea is to discuss and debate the issues and come to a reasonable, rational conclusion. Not everybody will get 100 percent of what they want - that's what compromise is all about. There are definitely certain elements out there that need to understand this - political gridlock solves nothing. Learn to compromise, learn to "bridge the gap," and we'll all be better off.
