Candidate Fundraising and Expenditures
Candidate "electability" is simply how likely it is that the candidate can run for elected office and win. A number of qualities are involved in electability. They include:
name recognition
reputation
experience
likability
funding
speaking ability
appearance
grasp of issues and possible solutions
New online tools make it possible to easily compare he amount of money a candidate has raised, been loaned, and has spent. Looking at their comparative financial strength can help narrow down your choices. Comparing their campaign finances is especially helpful in the primary election where there are several candidates to consider.
Perhaps some of those primary candidates have raised such a comparatively small an amount that means it will be virtually impossible to win a statewide election or in a large district that covers multiple counties. Their electability is not great, so you may want to focus on deciding who may be electable in that race.
Money is, of course, not the only important factor and sometimes candidates with less money can win. However, in a state as large as Texas, to educate voters about a particular candidate across multiple counties or the entire state takes a certain level of finances.
