If political issues actually split along the 95%/5% lines that correspond to that minority, then the 5% are effectively voiceless however you cut it. Another possibility is that most issues aren't about that minority group and you see something like republican:democrat:minority::42:43:5 split. Now the rep for that 5% has a ton of leverage to exchange, eg, votes for republican issues in exchange for republican support for minority issues.
