How can I reset the score after the results to 0 - 0?

#include <LiquidCrystal.h>

LiquidCrystal
lcd(12,11,5,4,3,2);

char candidate_1='A';
char candidate_2='B';
int vote_1=0;
int vote_2=0;

int state_1=0;
int state_2=0;
int result=0;

int button_1=6;
int button_2=7;
int button_result=8;

//Display message
void first_display() {
lcd.setCursor(0,0);
lcd.print("1-");
lcd.print(candidate_1);

lcd.setCursor(0,1);

lcd.print("2-");
lcd.print(candidate_2);

lcd.print(" choose!");

}

void setup() {
Serial.begin(9600);
lcd.begin(16,2);
pinMode(button_1,INPUT);
pinMode(button_2,INPUT);
pinMode(button_result,INPUT);

}

void loop() {

first_display();

state_1= digitalRead(button_1);
state_2=digitalRead(button_2);
result=digitalRead(button_result);

if(state_1==HIGH) {
vote_1++;
lcd.clear();
delay(1000);
lcd.print(candidate_1);
lcd.print(" selected");
Serial.print(candidate_1);
Serial.print(" selected");

delay(2000);
lcd.clear();

}

if(state_2==HIGH) {
vote_2++;
lcd.clear();
delay(1000);
lcd.print(candidate_2);
lcd.print(" selected");

Serial.print(candidate_2);
Serial.print("    selected");

delay(2000);
lcd.clear();

}

if(result==HIGH) {
lcd.clear();
delay(1000);
lcd.print(candidate_1);
lcd.print(" ");
lcd.print(vote_1);

  Serial.print("    ");
  Serial.print(vote_1);
  
  lcd.setCursor(0,1); 

  lcd.print(candidate_2);
  lcd.print("    ");
  lcd.print(vote_2);

  Serial.print("    ");
  Serial.print(vote_2);
  
  delay(4000);
  lcd.clear();

}

}
