1846–47 United States House of Representatives elections

The trend toward single-member districts culminated, as no multi-member districts featured. In 1845, partly motivated by the successful 1844 test of the electric telegraph between Washington and Baltimore, a major technological change enabling news and information to be transmitted almost instantaneously regardless of distance, Congress established a uniform date for choosing Presidential electors. Gradually, states would align nearly all elections with this date, though as of this election, only three states had done so. Two House seats were added for the new state of Wisconsin, which was unrepresented for most of the first session. == Special elections ==
