In politics, a big tent or catch-all party is a political party seeking to attract people with diverse viewpoints and thus appeal to more of the electorate. This is accomplished by appealing to a very limited number of issues, characteristics and/or goals, yet, capable enough to create the degree of unity necessary to fulfil said objectives. The big tent approach is opposed to single-issue litmus tests and ideological cohesiveness, conversely advocating multiple ideologies and views within a party.
